I've been saving this one, and I finally had a solid bit of time, so I finally gave it a spin... a spin straight to completion!
Short version, probably my favorite game in the series to date!
Good graphics, especially the new character portraits! They are beautiful. It's a shame that they weren't all completed, but I imagine time got tight. What's there is really good though. The music is great as always, and the SFX are all good too.
I was worried going into this one that it'd be too hard. I saw many players saying it was. I'm also not a bullet-hell aficionado. But you know what? The difficultly felt PERFECT to me. I'm not saying that adding an easy-mode so players have options would be a bad thing... but I found the current difficultly just the right balance of challenging and satisfying. I thoroughly enjoyed the current balance.
The gameplay itself took me a minute to understand, but once I did I loved it. I've never played "Shoot the Bullet" so it was all new/fresh feeling to me. The dating VN aspect was all nice. If I had to nitpick anything, I guess maybe a little more work on the writing/dialogue could improve it a little. It wasn't bad or anything, just maybe not as engaging as the gameplay sections. Still, I appreciated all the routes and options. I think Cornelia's was my favorite, from a dating standpoint.
A couple of bugs/issues. During Ophelia's final date scene(I think it was her anyway), Cornelia's name and portrait appeared a couple times, but it didn't seem like it should have been her. That was the only I time I noticed anything like that though.
A very specific bug I found on Firefox: During the tutorial, if I take the first photo in Fullscreen mode, the entire screen gets "locked" into a clear screen of Cornelia and Angelica and the BG, and stays that way until I lose. I can hear the game playing and move around, and get hit. But I can't really play. If I start the tutorial in small-screen, it works fine. After that first photo, going fullscreen also seems fine from that point on. Though I didn't do tons of testing... ultimately I played it on Chrome instead.
Anyhow, this is one of the best games I've played for this jam so far, and definitely my favorite to date of the Tengoku series. Awesome work!
